Description

Technical Field

[0001] The invention relates to the field of aircraft cabin external mounting transfer equipment, and in particular to a novel transfer transition beam with a stable structural system. Background Art

[0002] When an aircraft needs to hoist a missile launcher outside the cabin, the missile launcher cannot be directly hung on the universal hanging beam of the fuselage. Generally, a transfer transition beam is needed to connect the missile launcher and the universal hanging beam of the fuselage. The transfer transition beam can bear and transmit the ejection force, stopping force and lateral force of the hanging object. The existing transfer transition beam lacks an effective stopping mechanism, which easily causes the missile launcher to shake during the flight of the aircraft or the missile launch, thereby affecting the stability of the missile launcher suspension and the missile shooting accuracy. Summary of the invention

[0003] Based on the above technical problems, the present invention provides a new type of transfer transition beam with a stable structural system, which solves the problem that the existing transfer transition beam lacks an effective stopping mechanism, which easily causes the missile launcher to shake during the flight of the aircraft or the missile launch process, thereby affecting the stability of the missile launcher suspension and the missile shooting accuracy.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0005] A new transfer transition beam with a stable structural system includes an integrally formed hook, which is composed of a crossbeam and hooks arranged on the front and rear sides of the lower end of the crossbeam. The front and rear sides of the crossbeam are respectively fixed with a front hanger and a rear hanger for connecting with a universal hanging beam of a machine body. The front and rear sides of the crossbeam are also provided with stoppers to prevent the universal hanging beam from shaking.

[0006] In the present invention, when in use, the transfer transition beam is integrally hung under the aircraft universal hanging beam by using the front hanging and the rear hanging fixed to the cross beam, and then the hanging ear of the missile launcher is placed into the hook groove by using a bomb hanging vehicle or other hanging devices, and the position of the missile launcher is slightly adjusted so that the hanging ear notch is aligned with the hook. To prevent the missile launcher from shaking, the missile launcher is stopped by the stoppers installed on the front and rear sides of the cross beam. In addition, the cross beam and the hook of the transfer transition beam hook are integrally formed, and the hook is an integral structure that is stable and firm.

[0007] As a preferred embodiment, the stopper is composed of two stop components relatively arranged on the left and right sides of the beam, the stop component includes a stop arm, the stop arm is divided into a mounting portion vertically parallel to the beam and a supporting portion obliquely bent downward toward the side away from the beam, the mounting portion is fixedly connected to the beam by bolts, and a stabilizing component is provided at the end of the supporting portion.

[0008] As a preferred embodiment, the stabilizing assembly includes a threaded barrel passing through a through hole at the end of the supporting portion and vertically fixedly connected to the supporting portion, a screw rod is arranged in the threaded barrel, the lower end of the screw rod extends out of the threaded barrel and is connected to the stabilizing disk.

[0009] As a preferred embodiment, the lower end of the screw rod is connected to the stabilizing plate via a spherical head provided at the lower end of the screw rod.

[0010] As a preferred embodiment, the crossbeam is fixed to the inner cavity of the frame by screws, and the hook and the stopper extend out of the frame.

[0011] As a preferred embodiment, fairings are provided at both the front and rear ends of the frame, and the fairings are butt-jointed with the ends of the frame via a connecting frame.

[0012] As a preferred embodiment, the frame is assembled from a right side panel and a left side panel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The present invention solves the problem that the existing transfer transition beam lacks an effective stopping mechanism, which easily causes the missile launcher to shake during the flight of the aircraft or the missile launch process, thereby affecting the stability of the missile launcher suspension and the missile shooting accuracy.

[0015] (2) The present invention comprises a stopper composed of two stopper assemblies arranged on the left and right sides of the beam, the stopper assembly comprising a stopper arm, the stopper arm comprising a mounting portion vertically parallel to the beam and a support portion obliquely bent downwardly away from the beam, the mounting portion being fixedly connected to the beam by bolts, and a stabilizing assembly being provided at the end of the support portion. The stoppers on the front and rear sides of the beam contain a total of four stopper assemblies, and the front and rear stoppers adopt a four-point stopper structure, which can realize the lifting stop of the missile launcher and the arm restraint of the missile launcher in cooperation with the hook, and at the same time play the role of bearing and transmitting the reaction force, stopper force and lateral force generated by the missile ejection.

[0016] (3) The present invention comprises a stabilizing assembly including a threaded barrel that passes through a through hole provided at the end of the support portion and is vertically fixedly connected to the support portion, wherein a screw is provided in the threaded barrel, and the lower end of the screw extends out of the threaded barrel and is connected to the stabilizing plate. The screw is rotated in the threaded barrel, so that the position of the stabilizing plate can be adjusted by operating the screw, so that the stabilizing plate can be brought close to the missile launcher to stop and pre-tighten it.

[0017] (4) The present invention connects the lower end of the screw with the stabilizing disk through a spherical head provided at the lower end of the screw. After the stabilizing disk is pressed against the missile launcher, when the screw is rotated, the screw rotates to press the stabilizing disk so that the stabilizing disk does not rotate, thereby ensuring the pre-tightening effect.

[0018] (5) The present invention fixes the crossbeam to the inner cavity of the frame by screws, and the hook and the stopper extend out of the frame. The frame can play a certain protective role on the hook and the stopper, thereby improving the environmental adaptability of the product.

[0019] (6) The present invention provides fairings at both ends of the frame, and the fairings are connected to the ends of the frame through a connecting frame. The fairings are streamlined in shape, can adjust the airflow, and are conducive to reducing the force of wind on the transfer transition beam.

[0020] (7) The present invention facilitates the installation of the frame by assembling the right side panel and the left side panel. BRIEF DESCRIPTION OF THE DRAWINGS
